Abstract
The present invention relates to an ultrathin foil transferring and processing process for reducing curling and preventing folding of an ultrathin foil which may occur in the ultrathin foil transferring and processing process, and comprises: a step of coating or mounting an electrostatic-inducing material on both ends of a roll to form a charging part; a charging step of rubbing an ultrathin foil and the roll during the transferring and rolling of the ultrathin foil, to charge both ends of the ultrathin foil and the roll with positive or negative charges; and an electrostatic force applying step in which an electrostatic force is applied to both ends of the ultrathin foil simultaneously with or after the charging step and thus the curling of the ultrathin foil is reduced.
